With all my exams over, I finally found the time to do what I always wanted to: volt-mod my 9600 np. I first changed the stock heatsink (passive cooling) with a trimmed down Titan D5TB (aluminium heatsink) with a 60mm fan mounted over it. I had to improvise a holding mechanism since the heatsink was too big. I used screws with small springs attached to them to absorb any shocks. I used Arctic Alumina on the GPU. Then I soldered a 20k pot to the 5 and 7 pins of the IC called ISL6522CB (found on all 9600, pro and non-pros). Varying its resistance, I was able to modify the stock vgpu from 1.19V to max of 1.40, after which artifacts started to appear. At 1.34V I was able to overclock the GPU up to 510 w/o artifacts or crashing, but no further (artifacts would appear if I increased the voltage, or it would simply crash if I overclocked more). With the maximum overclock on the memory being at about 230 MHz (w/o any modding, *yet* ) and the GPU running 500 MHz, I got 11500 pts in 3DMark2001SE and 3150 in 3dmark03. I am currently looking for a mod for the vmem, since I already have heatsinks (made from yet another Titan D5TB) but I haven't attached them yet because I'm looking for a safe and almost permanent solution to do it. I'm expecting at least 250 MHz out of my memmory because they're 4ns Hynix chips.

========================================
Up till here is a copy-paste from another forum where I usually post, but vmods are not very frequent over there.
Now, with my vgpu done I'd like to mod the vmem.
I checked all the chips on my card and I noted down all the info on them, as can be seen in the following 2 pictures. I tried looking up their datasheets, and was able to find what I wanted for only 2 of them - ISL6522CB and CBT3257 - first of which was used to mod the vgpu; the 2nd I have no clue what it is used for. Now what I'm asking is either tell me what I need to do, or just tell me where I can find info on the rest of these chips. I suspect (though I am clueless about it) that the two IOR chips are responsible for the vmem.
Thanks for reading all this.
